Berk Lupina installed. It rides really well. No soreness or numbness anymore. I'm a little worried about durability as the saddle weighs only 70 grams. I also bought new shoes--Specialized SWorks Road shoes. Big upgrade from my entry -level Specialized road shoes from 2006! I like the saddle a lot more than the shoes. My feet aren't accustomed to such stiff shoes yet. Next up are pedals and then I'm done building the bike for a while, other than incrementally lowering the stem and ultimately cutting the tube.
